未找到活动尝试发送邮件时发生异常

Question

单击按钮时，我写了一段代码段来发送邮件。但是当我点击发送邮件按钮，我得到的logcat的一个ActivityNotFound例外...下面的代码...

public class appointments extends Activity { 

List<Strings> appnt=new ArrayList<Strings>(); 
ArrayAdapter<Strings> adapter=null; 
EditText name=null; 
EditText phone=null; 
Date date=null; 
Spinner spinner=null; 
EditText make=null; 
EditText miles=null; 



@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 
name=(EditText)findViewById(R.id.nametext); 
phone=(EditText)findViewById(R.id.phonetext); 
make=(EditText)findViewById(R.id.maketext); 
miles=(EditText)findViewById(R.id.miles); 



Button mail=(Button)findViewById(R.id.email); 
mail.setOnClickListener(onMail); 

Button reset=(Button)findViewById(R.id.reset); 
reset.setOnClickListener(onReset); 


Spinner hubSpinner = (Spinner) findViewById(R.id.spinner); 
ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.services , android.R.layout.simple_spinner_item); 
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
hubSpinner.setAdapter(adapter); 

} 
private View.OnClickListener onMail=new View.OnClickListener() { 
public void onClick(View v) 
{ 
Strings r=new Strings(); 
r.setName(name.getText().toString()); 
r.setPhone(phone.getText().toString()); 
r.setMake(make.getText().toString()); 
r.setMiles(miles.getText().toString()); 
final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
emailIntent.setType("plain/text"); 
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {"helpline@xyz.com" }); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,r.getServices()); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, r.getName()); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, r.getMake()); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, r.getMiles()); 
startActivity(Intent.createChooser(emailIntent, "Send mail...")); 
} 
}; 
private View.OnClickListener onReset=new View.OnClickListener() { 
public void onClick(View v) 
{ 

name.setText(""); 
phone.setText(""); 
make.setText(""); 
miles.setText(""); 


} 
}; 
} 

我应该使用另一个类onClicklistener或者我可以在这个活动本身显示邮件...

尝试切换类型： 的setType（ “消息/ RFC822”）;
